Blender 2.8 in Windows 10
2.8 is not released yet. I don't think it is very reasonable to expect technical support for installing software that is unfinished yet. You could try reinstalling graphics drivers, any other drivers that are not up to date on the PC, also you could try to re-download the latest build once in every few days and try if that works. Else than that - it is experimental software at this stage. Don't be surprised if it does not work yet.
